WILLIAM E. HEATH, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE OORONET BOTTLE-SEAL COMPANY OF BALTIMORE CITY, OF SAME PLACE.

BOTTLE-HSEAL;

SPECIFICATION forming part of Letters Patent No. 664,747, dated December 25, 1966.

Application filed January 20, 1900. Serial No. 2.128. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. HEATH, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Bottle-Seals; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in bottle-seals 5 and the objects and nature of the invention will be clear to those skilled in the art from the following description in the light of the accompanying drawings, illustrating one construction out of a number within the spirit and scope of my invention merely as an example for the purposes of description.

The invention consists in certain novel fea tures of construction and in combinations and in arrangements of parts and details, as more fully and specifically set forth and described hereinafter.

Referring to the accompanying drawings, Figure l is a perspective view of the neck of a bottle sealed by mechanism constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view through the bottle neck and seal, showing the plug before being forced in to compress the washer or sealing medium and before the plug has been expanded. Fig. 3 is a view corresponding to the illustration of Fig. 2, showing the plug forced in and the washer compressed and the seal effected. Fig. 4 is a detail perspective, enlarged, of the sealing-plug. Fig. 5 is adetail section, enlarged, corresponding to Fig. 3. Fig. 6 is a bottom plan view, enlarged, of the sealing-plug.

In the drawings, a is the neck portion of a bottle or other vessel or receptacle to which my sealing-plug can be adapted or applied. The top or upper end of said neck is formed with an annular seat or recess at around its mouth or the open end of its bore or dischargepassage. The floor of this recess preferably forms a flat annular step or shoulder, approximately as shown, although my invention is not so limited. From the inner annularedge of said shoulder, forming the floor of said recess, the inner surface of the bottle neck is usually increased downwardly in diameter (see a) to the inner edge of an annular stop-shoulder a This stop-shoulder faces upwardly, and the diameter of the interior of the bottle-neck at the inner edge of the said floor of the recess ct is greater than the internal diameter of the bottle-neck or liquid-pas sage at the inner edge of the stop shoulder (6, so that the plug, as hereinafter set up, can drop into the mouth of the bottle and its washer can freely descend with the plug and rest on said stop-shoulder, between which and the plug the liquid tight seal is effected.

Usually, although not necessarily, the inter-' nal diameter of the bottle-neck is not enlarged immediately below or'in that portion below and adjacent to said stop-shoulder.

The vertical wall of the top recess or seat is usually, although not necessarily, cylindrical, while the inner surface of the liquidpassage or bottle-neck between the floor of said recess and the annular stop-shoulder is suitably formed with an enlargement. In the specific example shown in the drawings this enlargement is annular and is attained by forming the bottle-neck internally and annularly undercut beneath said floor of the recess and above said shoulder. In other words, the surrounding wall can be tapered from the inner edge of said floor downwardly and outwardly to the surrounding edge of the stopshoulder, said wall in effect forming a truncated cone and forming the inner edge of said floor abrupt. I do not wish to limit my invention to this particular formation of the bottle-neck just described.

The sealing-plug is preferably hollow and cup-shaped and formed of a suitable thin ductile or pliable metal which will retain its shape when bent or expanded. These plugs are usually stamped out of some suitable thinsheet metal possessing the necessary strength to maintain the seal against accidental release and against the pressure of carbonated. liquids, and yet which will permit the easy proximately equal to or slightly less than the diameter of the liquid-passage at the inner edge of the floor of the said recess 0,, and consequently said external diameter of the portion b of the plug is greater than the diameter of the liquid-passage at the inner edge of the stop-shoulder. The lower end b of the plug is reduced in diameter, so as to fit or freely enter the liquid-passage at the inner edge of the stop-shoulder, and the annular ledge or stop-shoulder b" intervenes between the lower cylindrical portion 1) of the plug and the upper cylindrical portion 1) thereof. This step or stop-shoulder b" is arranged to oppose the stop shoulder of the bottle-neck and to cooperate therewith in compressing the sealing medium, such as washer c, and

thereby forming the liquid-tight joint. In the specific example. shown the upper end of the plug is formed with asurrounding flange b arranged and formed to enter the top recess of the bottle-neck. The plug for the purposes of extraction is provided with a thumbpiece, lever, or projection d, extend: ing from the circumference or edge of the upper end thereof to a point at the exterior of the bottle-neck, where. pressure in the proper direction can be applied to said projection to tilt the plug from the bottle. This projection is approximately rigid with the plug, so that in extracting the. plug the projection will not tear from the same, and thus defeat or prevent the completion of the extracting. op-. eration, but whereby the projectionand plug practically move together during the extracting. operation and both approximately, in effect, constitute a lever. The projection can be formed in any suitable manner and can be suitably attached to or formed a part of the plug. In the example shown in thedrawingsthe projection is formed by an upward and lateral deflection or loop. at an intermediate or central portion of a rod or wire 01, tightly fitting or partiallyembracing the up.- per. cylindrical portion of the plug beneath the flange b which retains or aids in retaining the said wire and projection to the plug. The flange is cut away or otherwise formed to. permit the upward passage of. the thumbpiece or projection, which in the example illustrated projects, upwardly through the plane. of said flange. near the edge of the bottle; mouth and such a distance above the same as to afford the necessary bearing-surface for the thumbin extracting the plug.

The washer c'is formed; of suitable sealing or packing material such as cork, pith, or a become seated on the stop-shoulder of the.

part b of the plug also slips down beyond'said is a pl ed the t p flan f h p an wire of the thumb-piece are forced into the engages the floor thereof and the top surface of said flange of'the plug is flush with or be-. ow the plane of the p. e ge o he. bottleneck, as sh wni Fig- 3. Whi eth p ug. is

' top recess of the bottle, usually until the wire hus he d. down y he pr ssure of the p ones tool a suitable implement expands the lower part of the upper cylindrical portion of the p ug, so that the plug is enlarge annulary r at ne r o e inte vals b ow the inner.

edge of the floor of the top. recess a] of the bottle, as shown at b. This expansion of the p 'hhk s P1 a a. p int mediat ly belo e wire of the mb-p e e. and. aho e. the shoulder b" of the plug, undelfi which the sealas is located, an the plug is ex:

panded in the specific, example shown, im-

mediately under the abrupt edge of the. fl or IOO r of t e p e s and the plug is hereby held in place with tile \YPtSherc mpressedand the liquid-tight joint maintained.

The. peculiar sealingdisk or plug per se I without the extractor thumb-piece is not claimed in this case, but forms the Sflbjepn.
